摘　　要：介绍了辽宁东五家子金矿控矿断裂的几何学、构造学与构造岩特征,指出NE向凌源—北票断裂与矿区东部的NW向二道营子断裂是金矿成矿的导矿断裂,二断裂旁侧的次级NW向与NE向断裂为金矿的容矿断裂。两组断裂均为长期多次活动断裂,早期活动具强烈韧性变形特征,晚期在韧性剪切带基础上再叠加脆性断裂。在此基础上探讨了两组断裂的控矿规律。This petrology and paper introduced geometry, structure, microstructure features of mineralizationcontrolling faults, pointed out Fault and NW Erdaoyingzi Fault that NE Linyuan-Beipiao are mineralization - leading faults, the NE and NW secondary faults beside them are mineralized faults. Two sets of fault are all long-lived faults. They exhibited sharply ductile deformation in early activities and superimposed brittle deformation in later activities. Their mineralization- controlling regularity was also discussed. ＂
